In fact I have tried it both ways. Once by downloading the binaries and once by pointing the package to the URL to the German binaries. Either way en-us got installed.
Yes, it did download the German-language binary prior to publishing it to the WSUS server
I also checked the .cab file associated with the package and double checked that it’s the German installation file. Again when I copy that installer file from the cab file and run it on one of the PCs it works fine but when its being pushed via SolarWinds it installs the en-us version.
But I understand your confusion – maybe I’m missing a step somewhere along the line? Could you kindly point out the steps involved in creating a custom package for Mozilla Firefox in German? So I can be sure I didn’t miss anything
Thanks
